Well worth a read....

Well I'm very happy with my Gateway gaming laptop that I purchased in 2009. It will handle video editing with AVCHD using Vegas Movie Studio 12 just fine. It has become my desktop replacement computer so I use it for Quickbooks, Excel, Word and many other programs.

[Steve Grisetti]

I always knew laptops were built for portability rather than speed -- but I wasn't aware there was that much of a difference with identical processors!

Does anyone have any idea why this is? The hardware doesn't care whether it's in a small box or a large box, right? Why are the difference between benchmarks so extreme?

[Bob]

The processors aren't identical. Processors designed for mobile use run at a lower clock speed and have a smaller on-chip cache to reduce power consumption. Both factors reduce performance.

[TreeTopsRanch]

It's also a cooling problem. Lower clock speed means it will run cooler.

[Steve Grisetti]

Thanks, guys. I definitely learned a lot!

Speed requires power, not only in the cpu, but also in the motherboard design. If the compact mobos in laptops worked as fast and as well as desktop ones do then we would see small compact mobos in desktop machines too. A laptop is set up to conserve energy for battery life anywhere it can, so performance suffers. I have a Core i7 920m which is not the same as a core i7 920. I have a desktop core i7 860 which is much faster than the laptop.

didn't reali e

wow e neither y keyboard is going on y old laptop urrent laptop in for replaeent of speakers and keyboard enter key does not work nor lots of keys on botto row so it sees silly to think of etending warranty for laptop sine they (lenoo) hae had it 3 weeks already beause they annot get speakers So what's up for desktop spes these days? I'e notied soe hae ore than y urrent 16 gigs ra frustrating! oputer quits no ore os adobe loud rats!

[TreeTopsRanch]

Huh?

[John 'twosheds' McDonald]

Wow, Paz. You're definitely having keyboard problems there but I got the drift of what you were writing, all except the very last bit.

oputer quits no ore os adobe loud rats!

puter quits OS gone says bill gates/ adobe gone to kloud/ RATS!/ stupid to add warranty to laptop/ 3 weeks waiting for speakers still with warra ty/ IB/\/\ = 0 speakers-parts/ repair laptop has 16 gigs RA/\/\ / folks here with 32? / what speks to look for for desktop? ab defghijkl nopqrstu w y / no return-enter / frustrated /better?

[_Paz_]

no kopy / no paste either/ not sure if kontrol works or not /

[John 'twosheds' McDonald]

For desktop specs my preference would be for a Z77 motherboard, i7 3770/3770K processor and at least 8GB RAM. Opsys Win 7 Pro 64 bit.

/\/\otherboard brand? / thanks!

Kan laptop RA/\/\ work in a desktop /\/\otherboard?
